I know the county was talking about this new technique, as well as another proposition to do away with the breaths. So far they are saying that the chest compressions are shown to let in air. I always found it strange that during the teaching they didn't focus on the breaths very much, but stressed the compressions very hard. Personally at work I am required to carry a barrier device, and I also have on my keys just in case. I would rather look back and say "damn, that guy died, but I did everything I knew to try to save him." Instead of "Damn, he died, and I just sat there watching."
